This functionality is available in EcoBRASxxxx-LIC license.
BRAS functionality allows the service provider to implement the so-called Services Gateway to restrict users access speed to IP services and data transmission services in both directions, to disconnect subscribers to forward them to the portal or web-page with the notice about the need to refill their account, as well as to demonstrate the information to subscribers by forwarding to the specified information portal.
An expected IPoE service model:
- the absence of encapsulation PPP, PPPoE, etc., means clean IPoE ;
- subscriber is uniquely identified by its IPv4 address within the provider network;
- aggregation or core (L3-connected subscribers) switch is a gateway for subscribers -not the BRAS;
- IP address to the subscriber may be issued statically or dynamically (by a third-party device, not EcoSGE) – using DHCP server associated with the billing system;
- device puts the speed limit of traffic(policing) the whole IP traffic, including the one that misses the NAT pools and is not subject to NAT translation. Non-IP traffic passes transparently.
BRAS permits to carry out short-term excess of traffic speed over the settlement (burst), duration of burst is limited by traffic volume corresponding to the first second to the contracted subscriber rate.
